HANDLE-FASTENER.

SPECIFICATION forming part of Letters Patent No. 255,166, dated March21, 1852.

Application filed November 3, 1881.

To all lwhom it may concern:

Be it known that I, ROBERT W. HARDIE, a citizen of the United States,residing at Albany, in the county ot' Albany and State ot` New York,have invented a new and useful Improvement in Handle-Fasteners, ot'which the following is a specification.

My invention isa handle-fastener; and it consists ot' a certain speeilicdevice, the construction and arrangement ot' the parts ot' which arehereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying drawings, Figure l represents the device applied toa hammer, in which a longitudinal section of the fastening in place inthe hammer is shown. Fig. 2 shows a side elevation of the handle and thefastening device with the hammer in longitudinal section, the devicebeing in position ready for application to the hammer. Fig. 3 showsdit'- ferent views 0f the locking-keys.

In these drawings, the eye of the hammerA is shown as flaring outwardly.The handle/B is formed with a reduced end, E, and shoulders e e; hut thedimensions of the handle at the widest part ofthe shoulders e e are notlarger than the smallest part ot` the eye, so that the handle may hepushed through the eye into a position shown in Fig. 2, in which theshoulders comealittle outside ofthe outer surface ot' the hammer.Plainly, the shoulders may project only so far as to he Hush with thatsurface, or may remain a little inside, it heilig only necessary thatthe handle shall project far enough to permit the application of thewedging or locking piecesff. These piecesf fare made with one sidesloping or inclined to the axis of the handle and the othersubstantially parallel therewith, the pieces fitting to the reduced endot' the handle, which, when the handle is in place,is within the tool.These pieces are also provided with teeth or projections t t, which fitinto corresponding notches Vand perfectly.

| in the reduced end of the handle. When they are in place upon theirsides on saidreduced end they are litted exactly to the eye, so thatwhen driven into the eye with the handle in the position shown in Fig. lthey tit snugly When in such position it will he obvious that thecentrifugal l'orce arising from the delivery of the blow will only tendto' wedge the tool upon its handle more tirmly,sol that the tool cannotfly oit', even if the handle be not tightly fitted in the eye. Thehandlemay he easily removed by driving it outward through the eye into theposition shown in Fig. 2.

I am aware that handles have been wedged in various ways, and thatwedges with roughened or serrated faces hearing upon the wood ofthehandle have heen driven hy the side of the handle, the reduced end ofthe handle being slopedto admit the wedge, and I do not broadly claimanysuch construction, the essential principle ot` my invention beinglimited t0 a handle which is passed through the eye, with a wedging orlocking piece provided with a projection or tooth placed against it, andwedged by drawing or driving hack the handle into its place in the eye.I desire only not to be limited to the'use ot' two of the pecesf f, as asingle one may be sufficient.

What I claim is- A 'handle-fastener consisting of the notched handleadapted to be inserted through the eye and to project therefrom at theouter side, the locking wedge piece or piecesf, titted thereto, incombination with the daring eye of thetool, whereby when the parts areall in place the centrifugal force is lnade to wedge the tool upon itshandle, substantially as described.
